For example, four residents receiving group therapy for an hour would each be assigned 60 minutes of care for the therapy session. When PPS was originally implemented, Medicare used 44 resident assessment categories to adjust rates. CMS expanded the number of RUGs from 44 to 53 in 2006 and from 53 to 66 in 2010. CMS intended that the expanded number of assessment categories would be budget-neutral while reflecting a greater range of care needs.
